Very nice french press, which is easily disassembled and clenead.
Where do they produce: see here (in German, but should be easy to understand) Tldr: Probably California
Erst das Schulkind, dann meine Frau und ich…nur die jüngste springt fröhlich durch die Bude während wir nicht mal wissen wie wir sie in die Kita bringen sollen.
War sehr lange nicht mehr so krank.
The system can only feed into your house line if there is an external 230V 50Hz power net working. The moment the net goes down there will be no power from your micro inverter to your house. It requires power to work and a stable 50 Hz similar to most bigger inverters.
If you combine a power station (battery) with the inverter, this battery might give you a 230V outlet with stable 50 Hz. But this is not the one you should plug back into your house (would require an unsafe cable).
Overall, lots of fear and wrong information in this thread about safety. There is a DIN norm for all of this and the current 800W limit exists to keep your power line from melting in the walls in the most extreme cases.

Does sound like California.
